Here's a Lovepedal Woodrow I built recently. It's probably mainly for guitar, but I actually think it sounds good on bass too! It uses and Electra Distortion circuit and was designed to emulate the tone of a cranked Fender 5E3 Tweed Deluxe amp.
I've made it True Bypass and also added a Gain knob. This pedal really reacts to how hard you play and how much gain there is.
I made a soundclip as well. First is clean, then full gain. Then I back it off to half and then just a little gain. Gets fuzzy at full gain and sounds cool. You can get just a little dirt out of it too if you want.
